Device damage The DE is completely sealed. Do not open the DE in the field. (2) Service life In situations where management and handling are correct, the life of the disk drive is five years when the DE surface temperature is less than 48°C. When the DE surface temperature exceeds 48°C, the life is five years or 20,000 hours of operation, whichever occurs first. Refer to Section 1.7 and 3.2 in Product Manual. (3) Exchangeable parts in field The PCA and the DE cannot be replaced separately in the field. Replace the whole disk drive. (4) Service system and repair Fujitsu Limited has a disk drive service system and repair facility. When making a request for repair or parts replacement, you should provide related information usually including: a) Model name of disk drive, part number (P/N), disk drive revision number, manufacture serial number (S/N), and date of manufacture of the disk drive b) Circumstances when the fault occurred c) − Date of trouble occurred − System configuration − Environmental conditions (including temperature, humidity, and voltage) Fault history of the drive d) Details of the fault C141-F059-01EN − Description of the fault − Issued command and specified parameters − Status (Status/Error register) − Interval of the fault − Other information for fault diagnosis 1-3 1.1 Maintenance Maintenance and Diagnosis Data corruption When asking for repair, save all data stored in the disk drive beforehand. Fujitsu Limited is not responsible for any loss of data during service and repair. (5) Notes on handling a. General notes a) Vibrations and shocks more severe than allowed will cause fatal damage to the device so be very careful. Be especially careful when unpacking the device. b) Do not leave the device in a dusty environment. c) b. Because the device uses GMR (giant MR head) and static sensitive CMOS semiconductors take the following precautions, be careful of the handling on the following points after the device is unpacked. − Use an antistatic mat, etc. in the environment for handling the equipment. The worker should also be physically grounded (e.g., wearing a wrist strap). − Hold by the DE section, do not directly touch the PCA unit unnecessarily. Unpacking a) Use a flat workplace, find which side of the pack is up and be careful not to have the wrong side facing upwards. Do not place the device directly on a hard table, place it on something soft such as a rubber mat. b) Be careful not to apply any excessive force to the packed device when removing the shock absorbing material. c) When taking the device out of the antistatic bag, be especially careful not to apply any excessive force to the PCA or to the interface connector section. d) Never ever remove the DE seal label and screws and the DE cover. c. Installation a) When the power is ON, do not change the switch setting, or connecting, or disconnecting connectors. b) Do not move the device or disconnect connectors with the power ON or until the disk drive unit comes to a complete stop after the power is turned OFF (about 30 seconds). d. Packaging a) 1-4 Place the device in an antistatic vinyl bag along with a desiccant (silica gel). C141-F059-01EN Maintenance and Diagnosis 1.1 Maintenance b) It is recommended that you use the shock absorption cushion material and packaging that contained the device when it was delivered by Fujitsu. If the same packaging material cannot be used, use a shock absorbent box that will transmit shocks directly to the device. When using this type of box, adequately protect the PCA surface and interface connector section. e. c) Place a label showing which side is up and clearly stating the notes on handling on the outside of the packaging. a) As a rule, deliver as it is packaged and keep the up side up. Delivery b) If delivering a single drive after it is unpacked, take it only a short distance. Also, use shock absorbent material to protect it against shock and vibration. Deliver an unpacked device in either of the allowable packed positions. Refer to Section 3.2 of the MHS2060AT, MHS2040AT, MHS2030AT, MHS2020AT Disk Drives Product Manual. f. Storage a) Store in dampproof packaging. b) Take care that the environmental requirements satisfy the non-operating environmental specifications described in Section 1.4 of the MHS2060AT, MHS2040AT, MHS2030AT, MHS2020AT Disk Drives Product Manual. c) To prevent condensation, do not subject the device to sudden changes of temperature. 1.1.3 Maintenance levels Because of its compact size and special repair requirements, it is recommended that the whole disk drive be replaced. This section describes maintenance on two levels. (1) Field maintenance (disk drive replacement) • Replacement at the user site. • Disk drive replacement requires ordinary tools. • Usually, the user, retailer, seller, or OEM trader will replace the drive. (2) Factory maintenance (parts replacement) • Only Fujitsu can perform maintenance at this level. • This includes maintenance training and assisting other OEM traders. The OEM trader usually assists the retailer and seller. • Use the factory level tools and test equipment. This includes recommended spare parts and repairing or replacing various parts. C141-F059-01EN 1-5 1.1 Maintenance Maintenance and Diagnosis 1.1.4 Disk drive revision number The disk drive revision number is a single alphabetic character followed by a single alphanumeric character. It is stuck on the DE and marked on the revision number label. Figure 1.1 shows the disk drive revision number label format. Disk drive revision number Firmware code/revision Figure 1.1 Disk drive revision number label (1) Revision number marking at delivery The machine revision number is indicated by crossing out up to the relevant number in the relevant alphabetic character row using = marks (see Figure 1.2). (2) Revision number change in the field When a part is replaced in the field or other modifications are made, the machine revision number may need to be changed. The level is indicated by crossing out the relevant number in the relevant alphabetic character row using ¡ marks (see Figure 1.2). (3) Firmware code and revision First 2-digit indicates a firmware code and rest 2-digit indicates its revision. Note: For a change of revision number after delivery, Fujitsu issues a “Change Request/Notice” and the disk drive revision number after the change. When a change is made at the user site, the revision number level should be changed as described above. 1-6 C141-F059-01EN Maintenance and Diagnosis 1.1 Maintenance Revision number mark when delivered A2 Revision Revision number change in the field A3 Revision Figure 1.2 Display of disk drive revision number C141-F059-01EN 1-7 1.1 Maintenance Maintenance and Diagnosis 1.1.5 Tools and test equipment At the field maintenance level, only ordinary hand tools are required for troubleshooting and repairing the disk drive. Special tools and test equipment is not required. Factory level tools and test equipment are beyond the scope of this manual. 1.1.6 Self-diagnostics The disk drive has the following self-diagnostics. These self-diagnostics allow normal basic operation of an isolated disk drive can be checked. • Initial self-diagnostics • Offline self-diagnostics (EXECUTE DRIVE DIAGNOSTIC [DIAGNOSTIC] command) 1.1.7 Test The disk drive test can be divided into the following three levels. • Operating test (See Subsection 1.2.1, “Operating test.”) • Diagnostic test (See Subsection 1.2.2, “Diagnostic test.”) Figure 1.3 shows the relationship between the test level and troubleshooting. Tables 1.1 and 1.2 show the check contents. 1-8 C141-F059-01EN Maintenance and Diagnosis 1.1 Maintenance Start Check the host system (Table 1.1) Yes Operation test with the host computer or test equipment System normal? No Analyze the system related failure Yes Disk drive replacement or repair Test acceptable? Yes Continue with the operation No Disk drive normal?

No Disk drive failure analysis (Table 1.2) Yes No failure Figure 1.3 Test flowchart C141-F059-01EN 1-9 1.2 Operation Confirmation Maintenance and Diagnosis Table 1.1 Status register contents Status bit Contents BIT0=1 Shown in Table 1.2 BIT1, 2 Normal. BIT3=1 (1) Check whether vibration is transmitted because of the way the disk drive is mounted. BIT4=1 (2) Check the power, cable, and connector. BIT5=1 (3) If it is concluded that the disk drive is the cause, replace the disk drive. BIT6=0 BIT7=1 Table 1.2 Disposition for error register contents Error bit Method of disposition BIT0 BIT1 BIT4 BIT6 If it is concluded that the disk drive is the cause, replace the drive. BIT2 BIT7 (1) Check the status of the host, cable, and drive. 1.2 (2) If it is concluded that the disk drive is the cause, replace the drive. Operation Confirmation 1.2.1 Operation test When the host computer is processing data, the disk drive monitors disk drive operation errors including data, command, and seek errors. The host is notified of the error that the disk drive detected and the user is notified of its result. The user may notice intermittent and indefinite failures such as overlong execution time, abnormal noise, abnormal odor, or failures in particular processes. The failure reported in the operation test will need further investigation. To ascertain the cause of the disk drive failure reported, the disk drive can be replaced. Failures in the operation test are often not caused by the host system. For example, not having enough power supply reserve, a loose cable connection, no timing and mechanical reserves, or relationship with other systems. In normal operation, the disk drive itself or the host determines the processing (return or halt) following the detected failure state. 1-10 C141-F059-01EN Maintenance and Diagnosis 1.3 Troubleshooting Procedure To troubleshoot the failure reported in the test at this level, accurately reproduce the condition that caused the failure. Then, by replacing the disk drive, try to separate the fault from the other sections of the disk drive host system. 1.2.2 Diagnostic test The diagnostic test is used to separate a confirmed disk drive failure to a disk drive subassembly or to check the disk drive performance. A test of this level usually includes a specific disk drive function or concentrated execution of a group of functions. The test is usually performed by a factory engineer and not where the failure was reported. The disk drive is tested using another host computer or test equipment. To troubleshoot the disk drive failure in the diagnostic test, the engineer will reproduce the failure condition. The engineer then isolates the failure to a subassembly or part of the disk drive. The procedures used in a test of this level great depend on the test equipment used. It is beyond the range of this manual. 1.3 Troubleshooting Procedure 1.3.1 Troubleshooting procedure This section describes the troubleshooting procedures for a disk drive failure at field maintenance level described in Subsection 1.1.3. In this section, troubleshooting is made to isolate the reported failure to the disk drive or a host system. Usually, troubleshooting is necessary only when a cause of failure is uncertain or unknown. When a cause of failure is clear (for example, abnormal sound in the DE or burnt parts on the PCA), a level of troubleshooting is low. 1.3.2 Troubleshooting disk drive replaced in field It is recommended that the whole drive be replaced in maintenance of this level. If replacing the drive corrects the fault, return the old drive to the factory for testing and repair. If the new drive shows the same fault as the one that was removed, the failure is elsewhere in the system. System level troubleshooting, shown in Table 1.3, is performed at the user site to isolate the reported failure to the disk drive or system. C141-F059-01EN 1-11 1.3 Troubleshooting Procedure Maintenance and Diagnosis Table 1.3 System level and field troubleshooting Check to be made Recommended work DC power voltage level Confirm that the DC power voltage is within ±5% of the standard value. When measured at pins 41 and 42 of the power supply connector, the +5 VDC must be 4.75 to 5.25 VDC. DC power ripple noise Check that the maximum ripple at +5 VDC power is less than 100 mV peak to peak and 200 mV peak to peak respectively. Power-interface cable connection Confirm that the AT interface cable is properly connected at the disk drive, power supply section, and control unit. Switch setting Confirm that the switch on the disk drive control PCA is set for normal operation with the host computer. Refer to Section 3.4 of the MHS2060AT, MHS2040AT, MHS2030AT, MHS2020AT Disk Drives Product Manual for switch setting. System cable Confirm that all cable connections throughout the system correctly connected. System diagnostic test To further isolate the failure, if it can be done, execute the system level diagnostic routine described in the host computer manual. Intermittent or indefinite error Check the AC voltage level at the power supply section and recheck the DC voltage level at the disk drive power supply connector. If the AC voltage level is abnormal, or if there is a lot of electrical noise, notify the user. If the DC voltage level is unstable, replace the power supply section. If possible, replace the disk drive. If the fault remains, the disk drive is not the case. For suggestions to isolate the failure further, refer to the hardware and software manuals provided with the system. 1-12 C141-F059-01EN Maintenance and Diagnosis 1.3 Troubleshooting Procedure 1.3.3 Troubleshooting at factory When the trouble is recovered by replacing the drive at field (Subsection 1.3.2), troubleshoot the replaced drive to isolate the trouble to the subassembly parts. To shorten the troubleshooting time and repairing time, gather the data, such as environmental data and other information, from the user and then return the failed drive to the factory with the media defect list to repair. At the factory, user environment is made and a reappearance test is performed. To reappearance a same trouble at user, the failed drive is connected to the host system. If no trouble occurs by the normal test, the reappearance test is performed by adding the voltage/temperature load using a disk drive tester or tools according to the user environment. When a trouble reappeared, troubleshoot the cause of failure. Then, replace the failed unit or parts. As this level maintenance is made by a factory, this maintenance level is beyond the scope of this manual. Device damage The disk enclosure must never to be opened in the field. Opening the disk enclosure may cause irreparable damage. C141-F059-01EN 1-13 This page is intentionally left blank CHAPTER 2 Removal and Replacement Procedure 2.1 Spare Parts 2.2 Disk Drive Removal This chapter explains the procedure for removing and replacing the disk drive. It is assumed that the reader has a thorough knowledge of replacing the complete disk drive and replacing the power-interface cable. When carrying out these procedures, note the following items. • Be sure to wear a wrist strap when removing the disk drive from the host system. • The disk drive must have been removed from the host system. • A power-interface cable to the disk drive must be disconnected. • Mounting is done by reversing the steps for removal. To carry out maintenance properly, observe the following: • Place removed screws and other parts where they will not get lost or damaged. • Keep a record of all maintenance work. • Tighten screws securely but not excessively. • Before touching the PCA, perform the FG (frame ground) to discharge any static electricity from your body. This ensures that the worker will not electrically damage the PCA. • Do not push the DE cover under any circumstances. C141-F059-01EN 2-1 2.1 Spare Parts 2.1 Removal and Replacement Procedure Spare Parts See Table 2.1 for the model and parts numbers to order the replacement disk drive.

Therefore, for actual working procedures, the specific conditions necessary for each system must be determined. The general removal procedures, with notes, is as follows. a) Disconnect the power-interface cable. b) Remove the screws that attach the drive and remove the drive from the system cabinet. c) When storing or transporting the drive, pack it an antistatic bag. To protect the device from damage and prevent the worker getting hurt, observe the following cautions and precautions in Subsection 1.1.1. Damage or Device damage 1. Perform any removal after the system power is completely disconnected. The cable must not be disconnected and the screws that attach the drive must not be removed with the power ON. 2. Do not move the drive until it comes to a complete stop (about 30 s after the power is turned OFF). 3. Perform the human body grounding to discharge any static electricity from your body.
